Other Parts Discussed in Thread: TPA3138D2, TPA3136D2
I have recently designed an Audio player using the TPA3112D1. I copied the reference design as close as possible. I am using a 24V power supply. Everything works as correctly, however I am failing the FCC test for conducted emissions, with 340khz and its harmonics causing failure. I have traced this to the audio amplifier, as it starts as soon as the amp is unmuted, as is mostly dependent of audio power levels. I am a bit puzzled what to try here.
The TPA3112D1 eval module says it passed FCC, but doesn't specifically say it passed conducted emissions. Is the full test report and setup photos available for this module?
